In very rare cases, the daemon registry will contain corrupted value:

• Daemon 1 starts on 54321 port, and it crashes, now daemon registry has entry {Daemon 1, 54321 port }
• Daemon 2 starts, it happens to allocate the same 54321 port. Now daemon registry has entries:
  • {Daemon 1, 54321 port }
  • {Daemon 2, 54321 port }
• A client tries to connect, and it selects Daemon 1. BOOM!

This appears to be happening again or still on some internal builds (@pbielicki can share).

Although, this doesn't appear to be a new problem (this is Gradle 4.6): https://ge.gradle.org/s/vwz7c42tmpgny/tests/:tooling-api:forkingIntegTest/org.gradle.integtests.tooling.ToolingApiClientCurrentJdkCompatibilityTest/tapi%20client%20can%20run%20build%20action%20with%20Gradle%204.6%20on%20Java%208?anchor=e30&focused-exception-line=0-38#1

This seems not happen for a long time (>1 year).
